Abstract
En 中文
Today, most innovation on Information Technology and Communication is cloud-centric and an increasing number of organizations believe that this transition is ever more unavoidable. With this increased demand for Cloud services, providers are facing many challenges regarding how to avoid outages and optimization of resource management since they impact directly in costs and profits. In this paper, we propose the cost-based allocation (CBA), a resource allocation system that takes into consideration the minimum availability level required by the user, and the minimum cost to allocate resources while complying with the service availability forum redundancy models. Results show that, considering occupation and cost metrics, our CBA algorithm presents the best overall performance between evaluated strategies.
